IMPROVEMENT IN WATEFt-ELEVATORS.4

Specication forming part of Letters Patent No. 35,679, dated May 26,1863.

To all whom it may concern Be it known that I, HUGH HAWKINS, of LockHaven,in the county of Clinton and State of Pennsylvania, have inventeda certain new and useful Improvement in Water-Elevators; and I do herebydeclare the following to be a full and exact description of the same,reference being had to the accompanying drawings, making part of thisspecification, in which- Figure l is a vertical transverse section at xx, Fig. 2, of a well-curb with my invention applied. Fig. 2 is avertical longitudinal section of the same at y y, Fig. l, showing adifferent position of the buckets.

Similar letters of reference indicate corresponding parts in the twogures.

The subject of my said invention is a simply constructed device forelevating water to any required height and automatically discharging thesame.

The invention consists in the Acombination of an endless chain, providedwith one or more buckets of peculiar construction, with a trough pivotedto the main discharge spout or trough, and operating substantially ashereinafter described.

It consists, secondly,in a novel device for discharging the contents ofsaid buckets.

To enable others skilled in the art to which my invention appertains tofully understand and use the same, I will proceed to describe itsconstruction and operation.

Ain the drawings may represent a wellcurb of wood, brick, or othersuitable material, erected at the mouth of a well, cistern, orreservoir.

B represents an octagonal pulley rigidly secured on a shaft, B. Overthis pulley works an endless chain, (l. The pulley B may be rotated bymeans of awinch or crank, D, of common construction, on the end of shaftB. The chain G is formed of links o and bars c', of nearly equal length,being so constructed to conform to the octagonal or other polygonalshape of the pulley B.

E E are buckets or vessels for containing water, the front part ofwhich, or the part whose top comes in contact with the pivoted trough,to be hereinafter described, is of semicylindrical form, and is formedwith a slanting top, higher in front than at the rear. The back orhinder part of the bucket is made iiat to adapt it to pass readily overthe pulley,

and is so attached to the chain C as to pre vent any obstruction beingodered to the motion thereof in its passage over said pulley and enableit while ascending to retain a vertical or upright position upon thechain, until it comes in contact with the pivoted trough above referredto.

To retain the water in the bucket until the latter reaches the properposition in its ascent, and then discharge it automatically, the bottomof thc bucket is provided with a large aperture, covered by a valve, e.The said valve closes by its own weight and that of the water upon it,until the bucket approaches its highest position, and is then raised bya lever, K, coming in contact with a cam-surface, H, on the side of thecurb.

F is the discharge spout or trough.

Gr is an inducting-trough, loosely pivoted at its respective sides, nearthe front part thereof, to the -inside of the trough F and projectingbackward to a considerable distance, its rear end being in verycloseproximity to the chain C.

I is a pawl working into the teeth of a ratchet-wheel, J, in customarymanner, to prevent the retrograde motion of the chain.

Operation The shaft B being rotated in 1 the direction indicated by thearrow, the

buckets are carried down within the well or cistern, and, being filledwith water, are elevated by the continued motion of the chain C. Eachsucceeding bucket in its ascent comes in contact with the rear end ofthe trough Gr, which trough, being loosely pivoted to the trough F, asexplained, is readily raised or elevated to a sufficient distance topermit the passage of the bucket. In raising the trough the bucket istilted slightly forward, but being higher at the front than at the rearside, and otherwise formed as hereinbefore described, little or no wateris spilt during the operation. When the bucket has passed the trough G,the latter, falling, resumes its normal position directly under thebucket. The bucket continues to ascend until it reaches the pulley B,and is about to pass over the same, when the end of the lever K, whichis directly beneath the valve e, being forced upward by its opposite endstriking forcibly against the cam-surface H, raises the said valve e andpermits the water to fall down onto the trough G, whence it iiows intothe main trough or spout F and out at the mouth thereof. rIhe flat backof the pulley B, chain C, buckets E, lever K, und y cani'bloek H, allconstructed and operating substantially as and for the purposes setforth.

2. The described combination of the hin ged trough G, with the buckets Eand trough F, for the purpose specified.

The above specification of my improvement in water elevators signed this14th day of February, 1863.

HUGH HAWKINS.
